That happens all the time without the system though. People who drive tiny little cars that turn on a dime routinely underestimate the space it takes for a big van or whatever to get out.
Does he? He said imagine if that feature is mainstream - so I'm assuming other cars also have this system.
Also, I don't understand why you'd blame the system if anyone gets "trapped" - you have your own eyes, no? Even when you park manually you have to judge if others can still leave. If the computer parks for you in such a way that makes others unable to leave.....then park somewhere else????? What is it with absolving people of personal responsibility all the time.
